How long does dog food last after opening? It depends on the food and the manufacturer’s directions. For dry kibble, Purina recommends using an opened bag within 4–6 weeks for best freshness. Check the package for product-specific instructions, and store food carefully to protect it from air, heat, and moisture.
How to store dry dog food
- Keep it in its original bag. Fold or seal the top tightly between meals. The bag also keeps the product name, lot number, and best-by date with the food.
- Choose a cool, dry place. The FDA recommends storing dry pet food below 80°F and away from excess heat and moisture.
- Use a container as an extra layer. For added protection, place the whole closed bag inside a clean, dry, airtight storage bin. If you pour kibble into another container, keep the identifying details from the original bag and wash and fully dry the container between bags.
- Use clean utensils. Wash and dry scoops and measuring cups after use, and keep the food stored securely away from pets and pests.
There isn’t one opening-to-discard date that applies to every dry dog food. Follow the directions from the food’s manufacturer, and contact them if you need advice for a specific recipe or package.
How to store opened canned or pouched dog food
Cover unused portions and refrigerate them promptly. The FDA recommends keeping refrigerated pet food at 40°F or below. Follow the product label for how long an opened can or pouch can be kept, and discard food that has been left out or no longer looks or smells normal.
Check the package before feeding
Use the best-by date and keep the lot number available. Don’t feed food from a damaged package or food that appears spoiled, has an unusual odor, or may have been exposed to moisture or pests. If your dog becomes ill after eating a food, stop feeding it and contact your veterinarian; the FDA also recommends reporting a pet food problem to the manufacturer.
